Each block is stacked on top of the previous one. Adding another block to the top makes all lower blocks more difficult to remove: there is more "weight" above each block. A transaction in a block 6 blocks deep (6 confirmations) will be very difficult to remove.

In this blogpost (http://www.idni.org/blog/projectroadmap) it is said that: "...from Apr 1 the price per token will be 20 cents, going up 5% monthly".But now it is Apr 12 and price is around 14 cents still. I do not like it.
